I tried this last week for an experiment. Just type in paracord and you'll find the threads.
I've noticed a lot of military guys do this on their service weapons because they cannot do actual trigger jobs. You are basically stressing the parts to conform and wear in to each other sooner than firing thousands of rounds.
The Norc trigger parts on mine were not square with each other causing grittiness, creep and squishy break. Once, squared, stoned, angle adjustment and polished it all works much better. [Sorry I don't have pics because to the naked eye you won't see much of anything and my camera won't do good closeups.]
With the paracord method I also noticed by pulling up hard on the hammer you are also increasing wear on the receiver hammer pin hole. Get too aggressive and you could have a problem later. Sloppy pin holes also make the trigger and hammer move around more.
Just an observation. YMMV
